FLEXIBLE SHIN GLE.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed April 25, 1918. Serial No. 230,789.

To all whom it may concern:

Be it known that I. ALBERT Anni: GRIS- won), a citizen of the UnitedStates, residing at Providence, in the county of Providence and State ofRhode Island, have invented a new and useful Improvement in FlexibleShingles, of which the following is a specification.

My invention has reference to an improvement in shingles and moreparticularly to an improvement inflexible shingles, whereby the shinglesare provided with means for securing the outer ends of the shingles inplace.

In the construction of roofs and the like on which flexible shingles areused, it is neccessary to hold down the free ends of the shingles so asto prevent bending or curling up of the shingles and allowing rain, snowor sleet to beat up under the shingles, thereby giving an unsightlyappearance and causing the roof to leak.

The object of my invention is to improve the construction of a flexibleshingle, whereby the outer or free end of the shingle is provided withmeans for securing the same in place, on a roof or the like.

My invention consists in the peculiar and novel construction of aflexible shingle, said flexible shingle being provided with means forholding down the outer or what has heretofore been the free end of theshingle and having details of construction, as will be more fully setforth hereinafter and claimed.

Figure 1, is a plan view of a portion of a flexible shingled roof, saidflexible shingles being provided with my improved means for securing theouter or free ends of the shingles in place on the roof.

Fig. 2, is a plan view of my improved flexible shingle.

Fig. 3, is an inverted plan view of my improved flexible shingle.

Fig. 4, is an enlarged detail longitudinal sectional View taken on line4. 4; of Fig. 3 through the shingle, and a V Fig. 5, is an enlargeddetail transverse sectional view taken on line 5. 5 of Fig. 3, throughthe shingle.

In the drawing 6 indicates the sheathing of a roof and 7. 7 flexibleshingles. The roof sheathing 6 may also represent the sheathing in theouter walls of a building.

The flexible shingles 6. 6 may be con- Each shingle 7 has its outer endor corner bent underneath and formed into flap 8 and a preferably flatwire 9 is formed trans-g versely through the flap by forcing one end ofthe wire in and out through the center portion of the flap. Whencompleted the wire 9 is secured to the flap 8, it lies parallel with theouter or lower edge of the shingle and the ends 10. 10 of the wireextend out beyond the edges of the flap to nearly the side edges of theshingle. The flap 8 is then cemented flat to the shingle or secured tothe shingle in any well known way.

In shingling a roof or the like with flexible shingles 6. 6 embodying myinvention, the shingles 6. 6 are laid diagonally. Each course is laid byplacing a shingle 6 of the next upper course over a shingle 6 of thenext lower course in a position for the ends 10. 10 of the wire 9 to gounder the edges of two adjacent lower shingles. The shingle is thenmoved upward and the ends 10. 10 of the wire 9 forced under the adjacentedges of two shingles in the lower course as shown in Fig. 1, therebyfirmly securing the lower end of the shingle to two shingles previouslynailed to the roof, in the lower course. The shingle is now nailedthrough its side corners to the roof and the same operation repeated forthe next shingle. In my im proved flexible shingle, the means forsecuring or holding down the outer or free end of the shingle forms apart of, and is sold with the shingle and the only operation requiredfor securing the free or outer end of the shingle, is the mere act ofplacing the shingle in place for nailing the shingle to the roof. As theact of securing the free or.

outer end of the shingle and putting the shingle in place for nailing isdone in one operation, a material saving in time is obtained, and a moreperfect roof, at less cost is constructed, than has heretofore beendone.

I do not wish to confine myself to the construction shown, as anyprojecting means on the outer end of the shingle adapted to go under theedges of adjacent shingles, could be used for the same purpose.

Having thus described my invention I clainras new:

1. A flexible shingle having a flap bent edges of adjacent shingles, inshingling aunder the shingle, sidewise extending members on the flap andadapted to go under the roof or the like, for the purpose as described.

2. A flexible shingle having a bent under flap, a member formedpof wiresecured to the flap and having outstanding ends adapted to go under theedges of adjacent shingles, previously laid, for the purpose asdescribed.

3. A flexible shingle having a bent under corner flap, a member formedof wire penetrating the flap and having outstanding ends adapted to gounder the edges of adjacent shingles previously laid, for the purpose as15 described.

.4. A flexible shingle adapted to be laid diagonally and having a bentunder corner flap, a member formed of-Wire secured to the flap andhaving outstanding ends adapted 20' to go under-the edges of adjacentshingles previously laid, said flap being cemented flat to the shingle,all for the purpose as described. 1

In testimony whereof, I have signed my 25- name to this specification.

ALBERT ABBE GRISWOLD.
